1. Frequency:

頻率≥20KHz ，可以分為低頻，中頻，高頻3段。

Frequency ≥ 20kHz, can be divided into low frequency, medium frequency, high frequency 3.

2.清洗介質(zhì)：

2. Cleaning medium:

采用超聲波清洗，一般兩類清洗劑：化學溶劑、水基清洗劑等。清洗介質(zhì)的化學作用，可以加速超聲波清洗效果，超聲波清洗是物理作用，兩種作用相結合，以對物件進行充分、徹底的清洗。

Ultrasonic cleaning is used. There are generally two kinds of cleaning agents: chemical solvent, water-based cleaning agent, etc. The chemical action of cleaning medium can accelerate the effect of ultrasonic cleaning. Ultrasonic cleaning is a physical action. The combination of the two functions can fully and thoroughly clean the objects.

3.功率密度：

3. Power density:

功率密度=發(fā)射功率(W)/發(fā)射面積(cm2)通常≥0.3W/cm2，超聲波的功率密度越高，空化效果越強，速度越快，清洗效果越好。但對于精密的、表面光潔度甚高的物件，采用長時間的高功率密度清洗會對物件表面產(chǎn)生“空化”腐蝕。

Power density = emission power (W) / emission area (cm2), usually ≥ 0.3w/cm2. The higher the power density of ultrasonic, the stronger the cavitation effect, the faster the speed, and the better the cleaning effect. However, for precision and high surface finish objects, long-time high power density cleaning will cause cavitation corrosion on the surface of the object

4.超聲波頻率：

4. Ultrasonic frequency:

超聲波頻率越低，在液體中產(chǎn)生的空化越容易，產(chǎn)生的力度大，作用也越強，適用于工件(粗、臟)初洗。頻率高則超聲波方向性強，適用于精細的物件清洗。

The lower the ultrasonic frequency is, the easier the cavitation in the liquid is, the greater the strength is, and the stronger the effect is. It is suitable for the initial washing of workpieces (coarse and dirty). High frequency ultrasonic direction is strong, suitable for fine object cleaning.

5.清洗溫度：

5. Cleaning temperature:

一般來說，超聲波在30℃-40℃時的空化效果好。清洗劑則溫度越高，作用越顯著。通常實際應用超聲波時，采用50℃-70℃的工作溫度。

Generally speaking, the cavitation effect of ultrasonic is the best at 30 ℃ - 40 ℃. The higher the temperature is, the more significant the effect is. Generally, the working temperature of 50 ℃ - 70 ℃ is used in the practical application of ultrasonic.
